The gender gap may be closing. In recent presidential elections, Democrats have done better with female voters, while Republicans have appealed more to men. So far this time, male swing voters seem to be looking more closely at the Democrats. After viewing all the candidate videos, our male subjects, when viewing still photos of the Democrats, showed significantly higher activity in the medial orbital prefrontal cortex, an area that is activated by rewarding stimuli, than they did while looking at pictures of the Republicans.
Women did not display such a one-party skew, but rather tended to react to individual candidates. So the traditional gender pattern of party preference may not be as prominent this year, particularly among men, and that may be good news for Democrats.
